My Mrs
My Mrs's family
The landscape out West
Openly friendly people (yes, Brits are friendly too but they need prompting)
Tex-Mex food
Sitting on the porch drinking beer in the sunshine chatting to the neighbours passing by
Going into a restaurant and getting served straight away and fed within 10 minutes
Being able to stop anywhere and get good food
The Trek corporation
The Specialized corporation
American music (off the top of my head Green Day, Third Eye Blind, REM, the Strokes, Incubus, Counting Crows, Fountains of Wayne, Moby and about a million others)
American films (almost every film I've loved)
American Radio - being able to listen to the above any time you want
Shops where the staff actually know what they are selling
Starbucks (and other places that have bothered to go beyond hot water and cheap coffee grounds)
Culvers
People who understand an appreciation of the outdoors without thinking you're some kind of freak
Did I mention my lovely Wife?
Maine
Oregon

American TV- HBo specially, but the Simpsons, the Wire, Battlestar Galactica
Hawaii
Friendliness and openness of the people (in most places), and their politeness and hospitality even when your world view and their's disagree
the National Parks
NASA
Pete Seger and Steve Earle
The attitude of shop and service industry workers that puts this country's to shame
That what's effectively a federation of 50 countries actually works pretty well.
The patriotism.

I don't get this 'no history' nonsense. The country was only founded 200 years ago, yes, but a hell of a lot has happened - and it's pretty much all documented. New York has a much longer, more interesting and more varied history than the city I live in - Cardiff.
